If I remember well, my series was considered a workaround to a bug triggered by an obsolete mechanism in the kernel. So it was advocated that we should get rid of that mechanism instead, and thus this series would be made irrelevant. However, removing that mechanism triggered a few regressions in some drivers, so it never went through, and my series was forgotten about. It's been in limbo ever since. Maxime
